Has the climate in Ouahigouya changed?

Ouahigouya has warmed about 0.5°F between 1992 and 2024.

About 0.2°F per decade, measured from Ouahigouya's official daily weather records, 1992–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Ouahigouya's warming is broadly in line with other cities in Burkina Faso — neither unusually fast nor unusually slow.

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.
